I was very attracted to the analytical aspect of Theravada Dhamma. Theravada Buddhists I spoke with encouraged me to investigate things honestly and sincerely without shame or the stigma of being called faithless which is often associated with many religious teachings in the world today. I have studied many philosophies and religious doctrines, and I was often met with hostility or anger if I looked into something for a while and then decided to move on rather than embrace that teaching. This has never been the case with Theravada Buddhism. One Bhikkhu I had been in contact with, even when I began studying a teaching which was in stark contrast to Theravada, continued to offer me friendly advice when I asked, and encouraged me to continue my study of that teaching until my mind had been satisfied.
People often told me the greatest warrior never reveals his skill unless it is absolutely necessary. He listens to those who brag their way is the best way and observes them without judgement or jealousy. His skill is revealed when he finds himself in a situation that requires it, but he reveals only what is required and when it is done he moves on without becoming intoxicated by his victory and ignores the fame accumulated with it while avoiding snubbery. He teaches those who make an honest and sincere request to learn, and he does not fear the chance they may surpass him in skill. To me this is the "Thera Nature." Like the great warrior, Theravada Buddhism welcomes all who sincerely wish to learn, but those who are not ready need not feel threatened. Those who feel threatened often feel so because they're not used to "an opponent who remains unmoved by braggery and intimidation."
I can not think of a war or battle that had the support of the Theravada Sangha at any point in time, other than the battle against one's own untrained mind, which has always been supported.
There is much more I can say but it all boils down to the main point I've made above. As the Blessed Buddha said, and this holds so much meaning to me and is to me the epitomy of "why Theravada:"
"Ehipassiko" (Come and See)
